Patent GB-833017-A (GB)
Title: A process for the production of toluic acids
IPC: C07C51/27
Filed: 1957-02-20
Abstract: The invention comprises a process for the production of toluic acids by hydrolysing o-and p-xylyl chlorides, in boiling or substantially boiling water, and oxidizing the xylyl alcohols or mixture of alcohols and xylyl ethers so formed with dilute nitric acid to obtain the corresponding toluic acids.  The hydrolysis is preferably carried out in the presence of the hydroxide of an alkali metal, ammonium or calcium, or in the presence of ferrous sulphate.  The nitrogen oxides produced during the course of the reaction may be re-transformed into dilute nitric acid by means of air and by absorption in water, and then used for the further oxidation of the xylyl alcohols.  Any calcium hydroxide used during the hydrolysis can be recovered if desired.  The toluic acids may be purified by filtering and washing with water and by azeotropical distillation with benzene.  The starting materials may be prepared by the chlormethylation of toluene by means of formaldehyde and hydrogen chloride.
